Description

  The present invention relates to a structure of a kind of grip, and more particularly, to a structure of a grip manufactured using a polyurethane foam material and having a light, comfortable grip feeling and excellent water absorption.

According to the standards of rackets (especially tennis rackets and badminton rackets), it is necessary to meet the international size norms, and within these norms, the designers help improve the effectiveness of use for each local Devise. For example, there are problems of equilibrium specific gravity, problems of elasticity and distortion, gut attachment technology or grip design. In addition, the grip is the only point of contact between the racket and the user, and at the same time is an important point for controlling the racket.
When choosing a racket, the user needs to consider the ability of the individual body and the habit of hitting the ball. The grip size is too tired and the sensitivity is weak, but the grip is too thin. It is difficult to grasp, and when a fast ball comes, the racket easily flips over. In addition, since a strong impact force is generated during tennis or badminton (or other racket) ball serve, the user may develop tennis elbow, etc. The main cause is the structure of the grip.
In general, in order to average the specific gravity of the grip of the racket, a light wooden material is selected and manufactured, and the grip main body is formed after being fixed to the end of the racket. However, since the wooden grip cannot cope with the user's grasping and comfort problems, a belt-like skin is wound around the surface of the wooden grip of the racket in a spiral shape. By using a skin-made epidermis, it is possible to provide the user with comfort when grasping and sweat absorption that absorbs sweat of the hand during exercise. However, the structure of the wooden material is not uniform at all points, and there is a problem that water penetrates. For this reason, the weight of the wooden grip is not average and the specific gravity is lost, which affects the effect of the ball serve when using the racket. In addition, the skin wound around the surface of the wooden grip is manufactured by leather, so it is not the best choice for its ability to absorb vibration and absorb sweat. This is also evident from the fact that the user often needs to adjust or replace the skin of the grip. In particular, since the user replaces and rolls the epidermis, it is necessary to pay attention to whether the intervals are the same when the roll is wound. If neglected, the grip feels bad and the effect of use is also affected.
In addition, as shown in FIG. 1, a general golf club mainly includes three parts, and includes a ball head 10 for hitting a ball, a grip 11 for a user to grip, and a ball head 10 and a grip 11. There is a shaft 12 that connects. The known grip 11 is usually made of various types of rubber, and the hollow grip 11 is provided so as to be covered with the end of the shaft 12 so that the user can easily grip it. However, since the grip 11 is an important key point for controlling the shaft, when the user selects a golf club, it is necessary to consider the size of the individual hand and the habit of hitting the ball. If the ball is too thick or too thin, it will affect the feeling of gripping and the direction of the ball.
The above-mentioned club is formed by the ball head 10, the grip 11, and the shaft 12, and has an average relationship of precise specific gravity. Therefore, even when the weight of any property changes, the total weight and swing of the club at all times It always affects the total weight of the time.
Further, as a further interpretation, since the club weight distribution has a certain ratio, the larger the total weight at the time of swing, the faster the speed of the ball head 10 at the time of hitting, thereby increasing the hitting force. The flying distance of the ball becomes longer. However, since the situation where the direction of the hit ball is biased is likely to occur, it is required to swing the club down precisely. However, since swinging down the club can be accomplished by practicing, many designers or users still care about the club swing weight value. Therefore, the designer lowers the weight of the grip 11 in order to increase the value of the weight of the club swing, and further reduces the thickness of the grip 11 to achieve the object. However, changing the size of the grip 11 appropriately reduces the effect of absorbing the vibration, and at the same time, it becomes difficult to absorb the strong impact force vibration generated at the moment of hitting the ball, thus directly affecting the direction of the hitting ball control. In addition, since the grip 11 is usually made of rubber, it has advantages such as preventing the surface from slipping at the beginning of use, providing a firm pawl, and having elasticity. After grasping, the surface is worn down, so that the characteristic of preventing sliding is lost and the effect of elasticity is also lowered. Furthermore, since the specific gravity of the rubber material becomes heavier, it is disadvantageous for raising the total weight of the club swing.

The known structure has the following drawbacks.
The structure of the wooden material has a problem that not all parts are uniform and the wood penetrates water. For this reason, the weight of the wooden grip is not average and the specific gravity is lost, which affects the effect of the ball serve when using the racket. In addition, the skin wound around the surface of the wooden grip is manufactured by leather, so it is not the best choice for its ability to absorb vibration and absorb sweat. In particular, since the user replaces and rolls the epidermis, it is necessary to pay attention to whether the gaps coincide with each other. If the skin is neglected, the grip feels worse and the effect of use is also affected.
The known golf club grip 11 is usually made of various rubbers. Since the grip 11 is usually made of rubber, the first one has advantages such as preventing slipping on the surface, providing a firm pawl, and having elasticity, but the rubber material has been grasped for a long time. After that, the surface is worn away, so that the characteristic of preventing slipping is lost, and the elastic effect is also lowered. Furthermore, since the specific gravity of the rubber material becomes heavier, it is disadvantageous for raising the total weight of the club swing.
The present invention provides a grip structure that solves the above problems.

In order to solve the above problems, the present invention provides the following grip structure.
It concerns the improvement of the grip structure, in particular the grip part of the exercise equipment.
